# Introduction Satoshi Protocol is the first Bitcoin Finance Network powered by satUSD, a Bitcoin-backed stablecoin. Mint satUSD with BTC as collateral across the Bitcoin Mainnet and L1s/L2s. To ensure stability, users need to maintain a minimum collateral ratio (MCR) of 110%. Besides over-collateralization, the protocol is secured by a Stability Pool where users deposit satUSD, which helps cover liquidations when collateral is too low. Other borrowers in the system also act as backstops to ensure the protocol remains stable. Explore further details on these mechanisms in the documentation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
